LLVM Debian/Ubuntu packages

Download

The goal is to provide Debian and Ubuntu nightly packages ready to be installed with minimal impact on the distribution.
Packages are available for amd64, i386 (except for recent Ubuntu), s390x and arm64 (aka aarch64). This for both the stable, old-stable and development branches (currently 12, 13 and 14).

Packages are built using stage2 and extremely similar to the one shipping in Debian & Ubuntu.

The packages provide LLVM + Clang + compiler-rt + polly + LLDB + LLD + libFuzzer + libc++ + libc++abi + openmp + libclc + libunwind + MLIR

Automatic installation script

For convenience there is an automatic installation script available that installs LLVM for you.
To install the latest stable version:

bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"

To install a specific version of LLVM:

wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh <version number>

To install all apt.llvm.org packages at once:

wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh <version number> all
# or
sudo ./llvm.sh all

Ubuntu

Precise, Quantal, Raring, Saucy, Utopic, Artful, Cosmic, Eoan and Trusty are no longer supported by Ubuntu. Repo remains available but not updated.

As i386 isn't supported by Ubuntu anymore, apt.llvm.org isn't either.

Verification using sigstore

Source, Debian tarballs and dsc files can be verified using sigstore/rekor.
This can be done with "rekor verify":

file="llvm-toolchain-10_10.0.1~%2b%2b20210327072807%2bef32c611aa21-1~exp1~20210327183412.212.dsc"
url="https://apt.llvm.org/unstable/pool/main/l/llvm-toolchain-10/$file"
sig_file="$url.asc"
wget --quiet https://apt.llvm.org/sigstore.public.key
./rekor verify --rekor_server https://rekor.sigstore.dev --signature $sig_file --public-key sigstore.public.key --artifact $url
echo $?

Or with "rekor search":

file="llvm-toolchain-10_10.0.1~++20210327072807+ef32c611aa21.orig.tar.xz"
url="https://apt.llvm.org/unstable/pool/main/l/llvm-toolchain-10/$file"
wget --quiet $url
sha=$(sha256sum $file|awk '{print $1}')
./rekor search --sha sha256:$sha --rekor_server https://rekor.sigstore.dev

Technical aspects

Packages are rebuilt against the trunk of the various LLVM projects.
They are rebuild through a Jenkins instance:
https://llvm-jenkins.debian.net

Bugs

Bugs should be reported on the LLVM bug tracker (label: packaging).

Workflow

Twice a day, each jenkins job will checkout the debian/ directory necessary to build the packages. The repository is available on the Debian hosting infrastructure: https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/.
Sources of this page, llvm.sh and others scripts are available on github:
https://github.com/opencollab/llvm-jenkins.debian.net/
In the llvm-toolchain-*-source, the following tasks will be performed:

upstream sources will be checkout
tarballs will be created. They are named:
- llvm-toolchain_X.Y~svn123456.orig-lldb.tar.bz2
- llvm-toolchain_X.Y~svn123456.orig-compiler-rt.tar.bz2
- llvm-toolchain_X.Y~svn123456.orig.tar.bz2
- llvm-toolchain_X.Y~svn123456.orig-clang.tar.bz2
- llvm-toolchain_X.Y~svn123456.orig-polly.tar.bz2
- ...
Debian .dsc package description is created
Start the jenkins job llvm-toolchain-X-binary

Then, the job llvm-toolchain-X-binary will:

Create a chroot using cowbuilder or update it is already existing
Build all the packages
Launch lintian, the Debian static analyzer
Publish the result on the LLVM repository

Note that a few patches are applied over the LLVM tarballs (and should be merged upstream at some point).

Extra

With the Jenkins instance, several reports are produced:

Building the latest nightly snapshot

Building LLVM packages from source is documented in a dedicated page.
